Its been known for a long time that plant-based diets can and will reverse heart disease. However, a recent study compared blood flow to the heart for those who eat plant-based diets to those who eat low-carb diet (aka #Atkins) diets. As expected, the those w/plant-based diet has less artery blockage. However, what is unique about this study is that some participants switched from plant-based diet to low-carb and their arteries commenced blocking after the switch! Very hard evidence these low-carb diets are not heart healthy.
